I received the cartridge flush kit a couple of days ago and had the chance to use it today. Even though many of you have way more experience with this than me I thought I'd put a few details down for reference.
For the Surecolor wide format printer you have to buy a single cartridge flush kit in parts rather than a kit which is offered for older models. Still I spoke to Wells at IJM and he had some pointers as well as knowing the parts I needed. I had originally bought a 350ml Piezoflush bottle and didn't buy any more as he told me it would be enough to charge the 700ml cartridge. I needed the chip, the cartridge, and a nozzle (which comes with a small syringe) to fit to the cartridge to prime it.
No issues filling and changing the cartridge except that a lot or air had to be pulled out of the cartridge as I was using so little ink. The original manual cleaning kit came with a large syringe but the tip I needed for pulling air came with a small one. It would have taken ages to pull the air with the smaller one (took about 8-10 "sucks" to get the ink changed with the bigger one). The video shows the instructor having to push down on a plastic part to click it in place before installing the chip but this doesn't seem to be necessary now.
Wells suggested either downloading the Adjustment program linked on their website (to 2Manuals.com) to do a Init Fill (which charges all the inks) or run a grey square to purge the LK I needed to clean. I started doing that with a 23x23 square on 24 paper, but no sign of the red flush after 6 squares to I bought the adjustment program and ran it (Win only and it gave a install warning which I overrode). After an interminable fill cycle I ran a nozzle check. The Piezoflush is very faint and I'm not 100% sure of the result but it looks like it may have improved a little, but the same blank lines may now have some flush lines on them, but are fainter than the other lines. I ran another square but I'm going to leave it overnight now and check it again tomorrow after a clean.
Any other suggestions?
Thanks
